Explanation

A pump-and-dump is a scheme in which a group first buys a thinly traded security cheaply, then spreads promotional messages to push the price up, and finally sells into the buying it created. The target is almost always an illiquid instrument: a small company share on an unregulated market segment (in Germany the Freiverkehr), a US over-the-counter stock, or a small crypto token, where a few hundred thousand euros of buying moves the price a lot. The course Trading Foundations covered the social side of "gurus" and signal groups; here we look at the mechanics and the law.

The four phases

1. Accumulation. The organisers buy quietly over weeks through several accounts, or receive shares from the company or an insider in return for the promotion.
2. Promotion (the pump). Newsletters, paid "research", Telegram or WhatsApp groups and social-media posts announce a "hidden gem" with a price target several times the current price. Messages are timed: "buy at 15:00 sharp", "do not sell before Friday".
3. Distribution (the dump). While followers buy, the organisers sell. Because they bought at the bottom, even a 40% fall from the peak leaves them a large profit.
4. Collapse. Volume dries up, the price falls to or below the starting level, and the group blames "short sellers" or deletes the channel.

The volume signature

Typical signs on a chart: daily volume many times higher than in previous months with no company announcement; a straight-line price rise for days with small pullbacks; the largest volume bar at or just after the top, which is the dump. Genuine news produces one volume spike on the day of the news followed by lower volume, not a staircase of rising volume before any announcement.

Why it is illegal

In the European Union the Market Abuse Regulation (MAR, Regulation (EU) No 596/2014) applies directly in all member states. Article 15 prohibits market manipulation and Article 12 defines it. Two definitions cover pumps: spreading information that gives false or misleading signals about supply, demand or price (Article 12(1)(c)), and scalping: publicly recommending an instrument after taking a position in it and profiting from the price effect without disclosing the conflict (Article 12(2)(d)). Article 20 MAR requires investment recommendations to be objective and to disclose conflicts.

In Germany the criminal penalties are in Section 119 of the Securities Trading Act (Wertpapierhandelsgesetz, WpHG): up to five years' imprisonment or a fine, and one to ten years when the offence is committed commercially or as a member of a gang. The Federal Financial Supervisory Authority (Bundesanstalt für Finanzdienstleistungsaufsicht, BaFin) investigates and hands cases to prosecutors. Buying on a signal is usually not a crime, but anyone who forwards the recommendation while holding the stock can be committing scalping. Compensation is almost impossible because organisers operate from abroad through anonymous channels.

As of 2025 BaFin has repeatedly warned about WhatsApp and Telegram groups that pose as staff of well-known German banks and steer members into apps run by unlicensed operators; check the current BaFin consumer warnings, because names change every few months.

Worked example

Hypothetical example: a share on an unregulated market segment trades at €0.20 with an average daily volume of 50,000 shares. Assumptions: no transaction costs, spreads or taxes; the organisers can sell their whole position during the pump.

1. Accumulation. The organisers buy 2,000,000 shares at an average of €0.20: cost = €400,000. That is 40 days of normal volume, spread over two months.
2. Pump. A newsletter and a Telegram group announce a target of €2.00. Daily volume rises to 3,000,000 shares and the price peaks at €0.80 within eight trading days.
3. Dump. The organisers sell their 2,000,000 shares at an average of €0.70: proceeds = 2,000,000 × €0.70 = €1,400,000. Profit = €1,400,000 − €400,000 = €1,000,000, a gain of 250% on their capital.
4. A follower. A group member buys 10,000 shares at €0.75 for €7,500 on day seven. Two weeks later the price is €0.15 and the position is worth €1,500. Loss = €6,000, or 80%.

Who paid the organisers' €1,000,000? The followers who bought between €0.20 and €0.80. The insiders' profit equals the crowd's loss, minus trading costs.

Common mistake

Practice activity

On paper: a share traded between €1.00 and €1.10 for six months with 20,000 shares a day. In the last five days volume was 150,000, 400,000, 900,000, 1,500,000 and 2,200,000 shares, and the closes were €1.30, €1.70, €2.20, €2.90 and €2.60. The company has published nothing. Which phase is this, what does day five tell you, and what is the loss of a buyer of 2,000 shares at €2.80 if the price returns to €1.05?

Key takeaways

• Pump-and-dumps need illiquid instruments; the organisers accumulate first and sell into the buying their promotion creates.
• The footprint is rising volume without news, a straight-line price rise and the largest volume bar near the top.
• Under MAR Articles 12 and 15 this is market manipulation; Germany punishes it under Section 119 WpHG with up to five years, or one to ten years for commercial or gang offences.
• Followers are the exit liquidity; the insiders' profit is the crowd's loss.
